Mystery Black Covering on Whirlpool Dishwasher
Our 2015 Whirlpool Gold Series dishwasher is covered in a dark residue on the inside unit walls and door. The dishes come out "clean", but the rust colored film occurs with every wash. We have run vinegar loads, super hot cycles with no dishes, checked the electric, checked the drains, cleaned the filter changed detergents. All to no avail. Any ideas? Note that if you wipe the inside of the dishwasher with a paper towel the towel will quickly turn brown/black with the residue. Do another load and it comes back. Any ideas what the residue is or how to end it? We are just outside of Chicago and have Lake Michigan water. Thanks!
We have been experiencing this same problem and have tried everything and can find no answers. We are thinking we will have to replace the washer even though it is only a couple years old. Thanks for any input :)
We have the same issue. We've had this machine for about 5 years and the problem just began. It must be a defective sealant that was applied on the bottom of the washer. I have checked my water, it does not have too much iron as Whirlpool suggests. I have city water and it looks crystal clear. Oct.2019
